BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Duesurlim’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact and early-flowering Petunia plants with numerous large flowers.

The new Petunia plant originated from a cross-pollination made by the Inventor in July, 2011 in Rheinberg, Germany of a proprietary selection of Petunia×hybrida identified as code number T08-3051-031, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number T08-1582-012, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2013.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2013 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesurlim’. These characteristics in combination distinguish ‘Duesurlim’ as a new and distinct Petunia plant:

-   -   1. Semi-upright and mounding plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Large white-colored flowers with yellow green-colored         centers.     -   6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have red-colored flowers with distinctive venation.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in flower size as plants of the new Petunia have larger flowers than plants of the male parent selection.

Plants of the new Petunia can be compared to plants of Petunia×hybrida ‘Duesurgrap’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Petunia and ‘Duesurgrap’ differ primarily in flower color.

Plants of the new Petunia can also be compared to plants of Petunia×hybrida ‘Sunlemon’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Petunia differed primarily from plants of ‘Sunlemon’ in the following characteristics:

-   -   1. Plants of the new Petunia were more compact than plants of         ‘Sunlemon’.     -   2. Plants of the new Petunia had larger leaves than plants of         ‘Sunlemon’.     -   3. Plants of the new Petunia flowered earlier than plants of         ‘Sunlemon’.     -   4. Plants of the new Petunia had larger flowers than plants of         ‘Sunlemon’.     -   5. Plants of the new Petunia and ‘Sunlemon’ differed slightly in         flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Petunia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia plant.

The photograph comprises a close-up view of typical flowers and leaves of ‘Duesurlim’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Petunia production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 16 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
